UNITED STATES P A TENT OFFICE.

PETER ONSUM, OF JACKSON, TENNESSEE, AND HENRY RICHARD DOHREN,

OF OHAMPAIGN, ILLINOIS.

GOVERNOR.

Patented March 19, 1907.

Application filed January 12, 1906. SerialNo. 295,708.

To LLZZ/ whom, it mxoy concern:

Be it known that we, PETER ONsUM and HENRY RICHARD DOHREN, citizens ofthe United States, residing, respectively, at Jackson, in the county ofMadison and State of Tennessee, and Champaign, in the county ofChampaign and State of Illinois, have invented certain new and usefulImprovements in Governors, of which the following is a specification.

This invention relates to a speed and stroke governor which is adaptableto various uses, and comprises mechanical and magnetic elements whichcooperate in effecting the desired results. For the purpose of showingclearly the adaptability of our invention, we have illustrated it inthis application for patent in connection with the stem of an ordinarybalanced valve.

The accompanying drawings are intended to illustrate the principles ofour invention. Hence We reserve the right to make various changes in themechanical details in the arrangement of parts and in the substitutionof mechanical equivalents for some of the parts shown. v

The primary object of our invention is to provide governing means whichwill take the place of the ordinary ball-governors or any other formofgovernor which acts through gravity or centrifugal force by substitutingmagnetic force therefor.

In the accompanying drawings, which form a part of this application,Figure 1 is a View in side elevation, showing our invention. Fig. 2 isan edge view showing the manner of mounting our governor, the scalebeing somewhat-larger than that shown in Fig. 1. Fig. 3 is a plan viewof the spider-- wheel which forms an element of our apparatus. Fig. 4 isa vertical section through the principal parts of our governor.

Referring to the details of the drawing, A represents asupporting-bracket which is formed with upright portions a a. and withpendent portion 0. and has secured thereto a standard a J ournaled inthe uprights a is a shaft E, for which ball-bearings are preferablyprovided. On the shaft a pulley D is mounted, which may be belted to anysuitable source of power and preferably driven from the crank-shaft bybelt, chain, or gears.

Between the uprights a. a spider-wheel B formed with a suitable hub withradial spokes b and an annular rim b Secured to opposite'sides of eachof the spokes by,

plates 12 and bolts b the latter passing through suitable openings inthe spokes, are two horseshoe-magnets b so arranged that their polesextend at right angles to one side of the wheel.

Loosely mounted on the shaft E is a Norway-iron disk 0, corresponding indiameter to the wheel B. This disk on its face adj acent to the wheel Bis formed with an annular flange c, which is arranged between the polesof the magnets and within their mag-' netic field.

0 represents an expansion coil spring, which is provided withtensionadjusting nuts 0 which engage the ends of a rod which passesthrough the spring. One end of the spring is secured to the standard aand the other end to an eyebolt 0 secured in the outer face of the disk,asclearly shown in Fig. 1.

Pivoted on the standard a is a pawl c, the free end of which engages anotch c in the periphery of the disk, thus preventing the latter frommoving backwardly. A spring 0 secured to the pawl and the support A,respectively, serves to hold the pawl in close engagement with theperiphery of the disk.

F is a crank-lever which is pivotally mounted on a pin f in the pendentlug a and has one arm connected to one of the pins 0 in the face of thedisk. The other-arm of the crank is pivoted by pin f 2 to the stem g ofthe valve G.

In a governor constructed substantially as described the rotation of thespider wheel or pulley, with its drive-shaft will produce r0,- tatingmagnetic field which will have a tendis mounted on the shaft E. Thiswheel is ency to carry the disk with it against the tension of thespring 0 and thus operate the crank E, cut-ofl rods, or any otherelements connected with the disk by any or all of the ins c. Theresistance of the magnetic field and the tension of the spring will beincreased in exact ratio with the speed of the engine on which ourgovernor is used.

It will be apparent that we may substitute electromagnets for thepermanent magnets shown and that the form or arrangement oftension-spring on the disk 0 may be variedv without departing from theessential features of our invention.

What we claim,

and desire to obtain by I the rotation of said disk, and means forpre-Letters Patent, is

venting the backward movement of said disk. 1. In a governor of theclass described, a In testimony whereof we affix our respecrotatablewheel, magnets secured to said tive signatures in presence of two.witnesses. wheel, a disk rotatably mounted in close; PETER ONSUM.proximity to said wheel and having a portion HENRY RICHARD DOHREN.extending into the field of said magnets and a tension device attachedto said disk, and adapted to resist the rotation of the disk.
